Reporting Selected Options
The modem can send a string of information to the DTE consisting of selected options using the following
command:
+MS?
The response is:
+MS:<mod>,<automode>,<min rate>,<max rate>
For example,
+MS: 11,1,300,33600 (shows default values)
Reporting Supported Options
The modem can send a string of information to the DTE consisting of supported options using the following
command:
+MS=?
The response is:
+MS:(list of supported <mod> values),(list of supported <automode> values)(list of supported <min
rate> values),(list of supported <max rate> values)
For example,
+MS:(0,1,2,3,8,9,10,13,64,69,74),(0,1),(300-33600),(300-33600)
